A: The fluttering of flags is a dynamic phenomenon involving three forces.

The primary one is a continuing pulling power because of the rope used to tie the flag to a pole.

The second power on the flag is because of gravity, which acts downwards.

The third power is accountable for fluttering is the wind. This power shouldn’t be fixed, each in magnitude and course. It may be better or lesser than the opposite forces.

The fascinating wavelike movement of a flag (made of material) outcomes when the wind pace goes above and comes under (in different phrases, oscillates about) a vital worth of the power equal to the flag’s weight.

Because the power because of the wind pace exceeds the burden, the flag tends to fly, and when it’s decrease, the flag sags.

Thus the speedy adjustments in wind pace across the flag ends in fluttering.
